GSD is the culmination of Dumas Paris' research in terms of improving comfort and optimizing product safety. This patented concept of the double shell allows to stop and to block the contamination resulting from the migration of mites and allergens.

The outer shell is an untreated textile which guarantees the comfort of a hypoallergenic contact. The inner liner receives a specific treatment and serves as a barrier to the harmful elements. This treatment contains a biocidal product SANITIZED® PL21-60 in compliance with EU requirements No. 528 / 2012. The two envelopes work in synergy to ensure maximum comfort and safety for humans and their environment.

The GSD label on the packaging indicates that your product benefits from this technology.
